data expansion:
lightcoin is inspired by bitcoin (BTC), and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol, and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places
litecoin is short for LTC, and its English name is litecoin. Litecoin stands for lightweight. The meaning behind litecoin is lightweight currency
1. Bitcoin generates a block every 10 minutes, while lightcoin LTC generates a block every 2.5 minutes. This means that lightcoin has faster transaction confirmation efficiency. Bitcoin transfer sometimes takes 1 hour or even longer to arrive at the account, but lightcoin generally takes less than 20 minutes to confirm
2. Since the LTC speed of lightcoin is four times that of bitcoin, and the reward of each block is the same as bitcoin, the total amount of money is four times that of bitcoin, which is 84 million lightcoins, which is higher than that of bitcoin<
3. Bitcoin adopts sha256 encryption algorithm, and lightcoin adopts script encryption algorithm. Compared with bitcoin, lightcoin LTC has a slightly lower computational load, which makes it easier to mine and more suitable for graphics card
(GPU) operation. At the same time, FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are better than sha256 used for bitcoin, More expensive.

in short, bitcoin ETF tracks the price of bitcoin. If the price of bitcoin ETF goes up, then the price of bitcoin goes up; On the contrary, if the price of bitcoin falls, the price of bitcoin ETF will fall. The difference between bitcoin and bitcoin ETF is that we don't have to worry about the bitcoin in our wallet being stolen by hackers, and we don't have to worry about where our bitcoin should be stored. This is a promotion on the technical level. If we buy bitcoin ETF, we will no longer have to learn how to operate bitcoin on the computer.
The purchase of CSI 300 ETF has more advantages than the purchase of traditional CSI 300 index funds. The purchase of ETF can save costs. Holding ETF only needs to pay 0.5% management fee and 0.1% custody fee, which is lower than the 1% management fee and 0.2% custody fee of traditional index funds
there is no stamp ty on ETF sales. If there is no special requirement, ETF trading shall be carried out according to the commission rate of stock trading. If the trading volume is particularly large, the commission rate of lof funds on the floor can be reced separately
if you are engaged in margin trading or securities lending, there are generally two fees. One is the transaction fee, which is the same as the ordinary transaction, and the other is the interest expense of the credit line of margin trading. According to the provisions of margin trading business, the margin trading interest rate is set at a certain proportion based on the benchmark interest rate of the people's Bank of China within six months

you can buy it for a few hundred yuan
it is recommended that you buy index fund 159902 or 160706
to buy a fund, you should never buy a fund in a bank. At least you should know that the bank doesn't work for you in vain, and the bank charges a commission - although it doesn't ask you directly, it asks the fund company - so you can understand that you shouldn't buy a fund in a fund company or a bank
to introce you to ETF index fund, you can also learn what is ETF index fund online. Now I'd like to briefly introce the advantages of buying ETF Index Fund:
1. Transaction cost advantage: you bring your ID card to the securities company to open a securities investment account, and use the "floor trading" method (like buying and selling stocks) to buy Index ETF funds. The transaction cost is not absolutely higher than 0.6%; And in banks, fund companies, securities companies OTC trading fund is generally 4%! Even as high as 5%< br />2 mobility. When you are in a hurry to use money, you usually have to wait four days to withdraw cash after selling funds in the way of over-the-counter trading in banks, fund companies and securities companies (if you meet Saturday, it will take six days; if you meet the national day and Mid Autumn Festival in 2009, it will take 12 days, ha ha). However, trading in the way of "over-the-counter trading" in securities companies is the same as trading in stocks, Sell today and get cash tomorrow!! Beautiful< br />3 Transaction convenience: no need to go to the bank to line up< br />4 It is not recommended that you superstitiously believe in fixed investment. Now banks and fund companies are advocating how good fixed investment is. Although fixed investment has its advantages, I absolutely don't approve of the fool form of fixed investment! They boast that it's profit driven - earn your commission. I suggest that you "invest intelligently", that is, you buy it one day every month. If you have a certain level, you can choose to buy your 200 yuan when the market falls sharply, so that your income will be better. And the best way is to have a long-term vision, expand the business cycle and operate in a large band. I in August 2007 large band operation (of course, to have a higher level) so far, yield 480%< br />5 Band operation: if you exercise to a very high level, you can switch between ETF index funds at different stages of the market and different styles to obtain excess returns! For example, 160706 tracks blue chip stocks and performs better than the other four ETF funds from June to October in 2007. When the concept junk stocks soared from January to may in 2007, 159902 performed brilliantly. In addition, ring the market recovery period (such as November 2008 to May 2009) and the last crazy period (October 2007 to January 2008), 159902 is also a good time to buy it<
the following is an introction to ETF index funds on the Internet, not my opinion:
the listed open ended Fund (LOF) of Shenzhen stock exchange is an open-end fund that can be listed and traded on the stock exchange, which is based on China's securities registration, settlement, exchange and trading system Based on the current situation of trading system, law and taxation, the ETF with Chinese characteristics is designed according to the characteristics of ETF. Lof is also a Listed Open-end Fund. After the issuance, investors can either purchase and redeem the fund shares at the designated website
or buy and sell the fund on the exchange. Lof provides a trading platform, based on which fund companies can turn closed-end funds into open-end funds, list open-end funds and so on, but it does not have the characteristics of index futures
ETF is the abbreviation of the English full name exchange traded fund, which literally translates into "exchange traded fund" (in fact, most of China used to use this name before). However, in order to highlight the connotation and essential characteristics of ETF as a financial proct, ETF is now generally called "trading open-end index fund". ETF is an open-end fund that tracks the change of "underlying index" and is listed on the stock exchange. Investors can buy and sell ETF just like buying and selling stocks, so as to realize the trading of index. Therefore, ETF can be understood as "stock index investment procts"
in essence, ETF is a special type of open-end funds, which combines the advantages of closed-end funds and open-end funds. Investors can not only apply for or redeem fund shares from fund management companies, but also buy and sell ETF shares in the securities market at market prices just like closed-end funds. However, the purchase and redemption of ETF must exchange a basket of stocks for fund shares or exchange fund shares for a basket of stocks, which is one of the main characteristics of ETF different from other open-end funds
compared with traditional closed-end funds and open-end funds, ETF has many advantages
first of all, ETF overcomes the defects of closed-end fund discount trading. The discount trading of closed-end funds is a common feature of global financial markets, and it is also a phenomenon that can not be well explained by classical financial theories so far, which is called "the puzzle of discount of closed-end funds". This phenomenon is particularly prominent in China. At present, the secondary market trading prices of 54 closed-end funds listed on the Shanghai and Shenzhen stock exchanges have an average discount of more than 30% relative to their unit net worth. Due to the discount transaction of closed-end funds, the development of global closed-end funds is shrinking day by day, and some of its original advantages are also covered up. ETF fund investors can not only trade in the secondary market, but also directly purchase and redeem a basket of stocks from the fund manager, which makes it possible for investors to arbitrage in the primary and secondary markets. It is this arbitrage mechanism that restrains the deviation between the secondary market price and the net value of the fund, so that the transaction price of the secondary market is basically consistent with the net value of the fund
secondly, compared with open-end funds, ETF funds have the characteristics of low transaction cost, convenient transaction and high transaction efficiency. At present, investors invest in open-end funds generally through banks, securities dealers and other sales agencies to apply for and redeem funds from fund management companies. The transaction fee of stock type open-end funds is generally more than 1%. Generally, the redemption money can only arrive at the account three days after redemption. Different funds need to go to different fund companies or banks and other agencies to purchase, so the transaction convenience is not very high. However, if investors invest in ETF funds, they can trade directly through the exchange according to the public quotation just like stocks and closed-end funds, and the funds will arrive the next day
finally, ETF generally adopts a completely passive index investment strategy to track and fit a representative underlying index, so the management fee is very low and the operation transparency is very high, which allows investors to invest in the constituent stocks in a basket of underlying indexes at a low cost, so as to achieve full diversification of investment and effectively avoid the non systematic risk of stock investment< Over the past 10 years, ETF has become the fastest growing financial proct in the world: American Stock Exchange (AMEX) launched Standard & Poor's index depository receipts (spdrs) on January 29, 1993. Since then, ETF procts have developed rapidly in the United States and even in the world. As of June 30, 2004, there are 304 ETFs in the world, and the asset scale has reached US $246.4 billion
at present, the 50ETF of Shanghai Stock Exchange designed in China is an open-end index fund that tracks the "Shanghai Stock Exchange 50 index" and is listed on the stock exchange. It is managed by Huaxia Fund Management Company and adopts a completely passive management mode to fit the 50 Shanghai Stock Exchange Index.
